AMSOIL Extended Life Synthetic Motor Oil
AMSOIL Extended Life Synthetic Motor Oil provides an intermediate choice between AMSOIL OE and premium Signature Series engine oils. It is engineered for motorists seeking enhanced synthetic protection and longer-lasting lubricant performance across demanding everyday driving conditions.
Protection Beyond Everyday Driving
Engine oil must resist heat, oxidation, deposits and viscosity loss while continuing to protect moving components throughout service. Extended Life Synthetic Motor Oil is formulated to maintain dependable protection as operating hours and kilometres accumulate, making it well suited to motorists who place greater demands on their vehicles or want to step beyond an entry-level synthetic oil.
Maintaining viscosity is an important part of sustained engine protection. Our article explaining stay-in-grade engine oil examines how mechanical shear can permanently reduce lubricant viscosity and why viscosity stability matters.
Find the Right Extended Life Oil
Always select the viscosity grade and specifications appropriate for your engine rather than choosing an oil on product tier alone. Use the AMSOIL Vehicle Product Finder to identify suitable products, or visit our Oil Standards Guide to understand common API, ILSAC and ACEA requirements.
